William K. Kapp III, MD, MS, FAAOS

Founder, Chairman/CEO
Dr. William Kapp had a vision to establish regional referral centers for medically complex patients requiring hospital-based post-acute care. Landmark Hospitals has grown into seven regional referral centers. Under his leadership, Landmark has implemented new information technologies that allow clinicians to easily document patient encounters and then follow and manage the patient upon discharge from our critical care hospitals across all post-acute settings, allowing for better outcomes and a seamless continuum of care.

Dr. Kapp served as managing partner and leader for Physicians Alliance Surgery Center in Cape Girardeau and was instrumental in its design, development, and certification. He served as its Founding President and Medical Director from 2000 – 2003 and on its Medical Board from 2000 − 2011. Physicians Alliance is a multi-specialty outpatient surgical center with four operating suites and over 30 staff members. In 2011, St. Francis Medical Center acquired partial interest in Physicians Alliance.

Dr. Kapp also served 15 years as managing partner for Orthopaedic Associates of SE Missouri, the region’s only orthopaedic center. Orthopaedic Associates is a 9-physican practice with over 70 employees. Under his direction, the group grew from five physicians and two offices to nine physicians and five satellite locations. Revenue grew over 300% under his leadership.

Dr. Kapp is a founding advisory board member of Missouri Physicians Mutual. MPM was founded in the late 1990’s as a Missouri-based 383 company to provide affordable medical malpractice insurance to a troubled market. MPM was able to grow from 10 physicians at its inception to well over 2,000, becoming the largest insurer in the state for physician medical malpractice insurance.

Dr. Kapp is a board-certified orthopaedic surgeon and a Fellow in the American Academy of Orthopaedic Surgeons, licensed to practice in Illinois, Missouri, Texas and Georgia. He has served on the Board of Directors of the Missouri Orthopaedic Association and has been chair of the Legislative Affairs Committee.

Until 2005, he served as flight surgeon in the US Air Force Reserves with the rank of Major.

Dr. Kapp received his B.S. in Biochemistry from the University of Georgia and his M.S. in Immunology and M.D. at the Medical College of Georgia, where he graduated with honors and was inducted into Alpha Omega Alpha, the medical honor society.
